TELEPHONE- RECEIVER ATTACHMENT.

Application filed October Our invention is a telephone receiver attachment to enable hearing by telephone Without having to hold the receiver to the ear.

An object of our invention is to provide a sound amplifying device having a horn and a stand on which the receiver may be placed whereby the sound from the receiver is carried through the horn giving considerable audibility, without the listener having to place his ear close to'the horn. Another object of our invention is to provide a stand for the telephone of the desk type whereby the telephone may be left on the stand and the receiver placed over the sound receiving openin on receipt of a call thus leaving the hands free to write memos or handle papers,

etc.

Our telephone receiver attachment comprises a stand or board adapted to rest on a desk or table and it is preferably made sufliciently large to hold the usual desk type of telephone set. A coned shaped receiver support with a sound receiving opening is con veniently located on the stand and a sound passage leads in the body of the stand or board to an upstanding horn. The receiver is placed with the ear piece down on its support and the sound passage and horn are proportioned to amplify the sound. We have found the conversation messages which have been difficult to hear, using the receiver to the ear are quite audible at a convenient distance from our attachment.

Our invention will be more readily understood from the following description considered together with the drawings in which Figure 1 is a perspective view of our telephone receiver attachment made in the form of a stand, showing the desk set on the stand, the receiver over the sound passage and the horn.

Figure 2 is a plan view of the stand with the desk set removed.

Figure 3 is a vertical sectional view on the line 3-3 of Figure 2 in the direction of the arrows, showing the receiver support,

the sound passage in the board and the lower end of the sound amplifying horn.

Figure 4 is a perspective view of trans mittcr standard showing an arrangement for wedging the receiver hook into its lowcred position to break the circuit so that the receiver may be left on the stand.

In the drawings, referring first to Figures 5, 1925. Serial No. 60,622.

1, 2 and 3, the telephone stand is designated generally by the numeral 1, and is shown as a board 2 with feet 3 secured to the corners to raise the board slightly above a table top. The board is made sufficiently large to hold the usual telephone set of the desk type designated by the numeral 4.

A frustrum of a cone-shaped receiver support 5 is secured to the top of the board and is constructed with tapered sides 6, a slight cylindrical portion 7 and a flat top 8. These elements are shaped to fit in the ear piece 9 of the ordinary telephone receiver 10. An aperture 11 extends vertically through the receiver supporting cone, con necting with a vertical bore 12 in the board. A sound passage 13 is formed in the body of the board leading laterally from the bore 12 to the up turned sound opening 14 which terminates at the surface of the board. A sleeve 15 is attached to the top of the board and forms a support for a horn 16, which is constructed with a gradually enlarging sound amplifying section 17 and with a belled mouth 18 turned horizontally.

The various sound passages and the horn are so proportioned to convey the sound from the diaphragm of the receiver, to amlify the sound and. to project it horizontaly convenient to a listener. The receiver support allows the receiver to be placed thereon with the diaphragm in close relation to the flat top 8, so that substantially all the efiective vibrations of the diaphragm are conveyed through the sound passages to the horn.

In Figure 4 we show a convenient way of holding the receiver hook in its down or circuit breaking position so that the receiver need not be removed from the receiver support on the closing of a conversation. A small wedge 21 is shaped to fit between the wall of the transmitter stand 22 and a lug 23 on the hook. A cord 24 secured to the wedge and. a standard always holds the wedge in a convenient position to insert after a conversation and to allow the ready pulling of the lugwedge on receipt of a call.

It is elieved the manner of use of our telephone receiver attachment will be obvious from the above description. However it may be stated that the receiver may be taken off the hook for out-going and in-coming calls and placed on the receiver support, which will let the receiver hook move u to make the circuit. Or if desired the receiver may be left continuously on the receiver support, using the wedge to hold the receiver hook down when the telephone is not in use.

Our invention may be adapted to use with wall telephones by supporting the board with merely the receiver support, the sound passages and the horn mounted thereon, on the wall in convenient relation to the wall telephone. Other modifications of o'ur'inve-ntion will be obvious; and the design in general features and specific details may be changed without departing from the spirit of our invention as set forth in the description, drawings and claim.

Having described our invention what we claim is A telephone support comprising in comtrum of a cone portion adapted to center tlie'ear piece of a telephone receiver when placed base down thereon, a horn support on the board the said board having a sound passage in the body thereof connectin the aperture of the receiver support an the horn support.

In testimony whereof we have signed our names to this specification.
